General system Kernel, boot, graphics & hardware

Hi Endeavouros,

I’m new here and hope find in this os all i need for an os,

But i’m stuck with a new install

I’ve installed endeavouros on a new partition on my 2TB HD, wich have many partitions such as efi, windows, tuxedo os, and personnal data…

I’ve already installed Endeavouros in ext4 with good reliancy in Grub, (updated from tuxedo OS) ,

Now I’ve discovered benefits of btrfs and snapshoot and i’ve reinstalled it in btfrs this time, but grub don’t reconize it,

Tried os-prober, update-grub…

Any idea on this issue ?

Hi and welcome to the forum @Bearout !
grub-btrfs
might be what you need.
Edit:
If you install EnOS BTRFS with a new EFI
and uncomment os-prober line in grub
you may check whether all other systems appears after
sudo grub-mkconfig -o /boot/grub/grub.cfg
Other fixes like
cd /path/to/your/btrfs/root
ln -s @/boot boot
ln -s @/etc etc
did not work for me

Not all versions of grub support btrfs. I am not sure about the grub that came with Tuxedo.

Hi @dalto and @eso thanks@esothanks for your help​:slightly_smiling_face:

Grub was installed with tuxedo OS in version 2.12

os-prober gives me only windows boot at /dev/nvme1p1@EFI[…]/bootmgfw.efi

And

btrfs-grub gives me detecting snapshots,

UUID of the root subvolume is not available

Yeah, I would install grub from EOS and see if that fixes it for you.
